ing-Machines land Wagons, of which the foltongue for up and down swinging movement,

lowing is a specicatlon.

The objectof my invention is to provide a combination hitch for a harvesting machine such as a corn harvester, and a wagon.

More particularly it is my object to provide such a combination hitch, whereby a harvesting machine such as a corn harvester, and also a wagon may be drawn behind a tractor or the like, the device being of simple, durable and inexpensive construction, and being so arranged as to permit sufficient play of the parts, so that they will not bind, and will permit the wagon or corn harvester to pro erly travel behind the tractor.

w ith these and other objects in view my invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which:

Figure 1 is a top or plan view of a com ination hitch embodying my invention.

Application led December 23, 1919. Serial No. 347,037.

upper and lower spaced strips 15 which eX- tend forwardly and receive between their forward ends a draft bar 16', to which said strips 15 are pivoted by means of the bolt 17.

Secured to the lower surface of 'the tongue 12 near the forwardV end thereof, just rearwardly of the truck 13 and extending down wardly from the tongue is a bracket 18 to which is pivoted, by means of the horizontal bolt 19, a cross bar 20.

Near the middle of the bar 20 from end to end there are provided wear plates 21 on the front, and rear of said bar, and back of the rear wear plate is a rearwardly opening short channel iron 23.

Extending across the bar 20, above and below said bar, are metal strips 24 which are pivoted to the channel 23 by means of an upright bolt 26.

,The strips 24 extend forwardly from the bar 20 and are twisted at their forward ends from horizontal to vertical position, as shown in Figs. 1 and 6.

Mounted in the forward ends of the strips 24 is a transverse bolt 27.

rfhe metal strip 28 is bent at its center around the bolt 27 for pivotally connecting the strip 23 with the bolt27, and the parts of the strip 28 are extended forwardly from the holt 27 adjacent to each other, as shown in Fig. 6, and are riveted together as at 29.

At the forward end of the strip 28, the y, ends thereof are spread apart, as at 30, and

receive between them the draft bar 16 to which the said ends are pivoted by means of a bolt 31.

Jllhe bar 2O is trussed or reinforced by means of a two-part rod 32. rihe eXtreme ends of the rod 32 are mounted respectively on bolts 19 and 33 extended through the bar 2O near the end thereof.

Mounted on the adjacent ends of the two sou parts of the bar 32 is a turn-buckle'34. Near its central part the bar 32 is held in a position spaced from the bar 20 by the following means.

Extended through the channel 23, the bar 20 and the wear plates 21, is an eye-bolt 35 which projects forwardly a substantial distance beyond the bar 20. Mounted on the eye-bolt 35 is a spacer sleeve 36. The eye of the eye-bolt 35 at its forward end receives the rod 32. as illustrated in Figs. l and 6.

Pivotally connected with the bar 20, at a point between the strips 24 and the end of said bar .opposite the tongue 12 is a coniro necting brace 36 which is also pivoted to the frame 10 by means of a bolt 37.

The connecting brace 36 is connected with For supporting the bar 20 and holding up thel left-hand end thereof, as illustrated in Fig. l, ll have provided .the following means:

A brace 41 connects the tongue l2 and the frame member 10 as illustrated in Fig. 1, and is located on the right-hand side of said tongue.

Supported on the tongue 12 near the rearward end thereof is a block 42.

The block 42 has a recess 43 in its upper surface. The block 42 is fastened to the tongue 12 by means of a 4bolt 44.

On the bottom ofthe tongue 12 is an angle-iron reinforcing member 45 through which the bolt 44 extends.

Resting in the recess 434 is a supporting bar 46, which is substantially horizontal and is. inclined diagonally with relation to the tongue 12, extending from position above the brace 41 to position above the bar 20, as illustrated in Fig. 1.

Mounted in the bar. 46, above the block 42, 1s an upright eye-bolt 47` which projects above the supportingbar 46. Mounted on the eye-bolt 47 above the bar 46 is a sleeve 48.

Extended through the eye at the upper end of the `eye-bolt 47 is a truss rod 49 which inclines downwardly from the eyebolt toward the opposite ends of the bar 46. At the rearward ends of the rod-49 and bar 46, an eye-bolt 50 is extended through the bar 46 and is secured to the rod 49, as illustrated in Fig. 3.

Mounted on the lower end of the eye-bolt 50 is an eye-boltl 50a one end of which is mounted in a turn-buckle 51. Received in the outer end of the turn-buckle 51 is the screw-threaded shank of a bolt 52, having the hook shaped head 53 which receives the brace 41. j Y

At the opposite end of the supporting bar 46 on the upper surface thereof is an anglelron bracket 54, vthrough which the truss rod 49 is extended, as shownin Fig. 6.

On the end of the truss rod 49 is a nut 55, by which the tensionl on said rod may be ad usted.

bar 46 isan eye-bo t the bar 20 is an eye-bolt 22. The eye-bolts :56 and 22 are detachably connected by a ihook '58.

BB. -Pivotally connected with the draft bar 16 the bracket 54 and the xtending throu 56. Extended through is a clevis device 59 to which is secured a chain or thelike 60 which may be connected with a tractor.

At the right-hand end of the bar 20 is a device for bitching a wagon to my combination hitch.

Mounted on the right-hand end of the bar 20 is a downwardly opening channel shaped member 61.

An eye-bolt 52 extends through the walls of the member 61 and through the bar 20 and is connected with a chain 63 which may be fastened to a wagon.

Pivotally supported on the upper surface of the member 61 by means of a pin or the like 64, is a transverse bar 65 having at its opposite ends upwardly extending members 66 and 67.

Pivoted to the upper edge of the member 67 is a locking bar 68, which extends to the left, as shown in Figs. 1 and 5 beyond the member 66;

At the free end of the bar 68 is a downwardly extending ange 69. Mounted on the under surface ofl the bar 68 is an angleangle iron 70, is a stop member 72 which is en a ed by a spring for normally tending to mogveig the locking bolt 71 toward locking position.

ln the upwardly extending member 66 is a hole for receiving the end of the locking bolt 71.

Extending forwardly from the right-hand end of the bar 20 is a chain or the like 73.

In the practical use of my improved' combination hitch, theJ hitch is preferably as-v sembled on the corn harvester in the manner hereinbefore described, and is preferably left as a permanent attachment thereto. The hitch is bolted to the corn harvester so that it, can be removed if desired.

It will be seen that the corn harvester can be drawn forwardly bythe tractor when desired by the use of my combination hitch. The bar 46 with its truss rod A49 supports the right-hand end f the bar 20, as herein clearly shown. l

Whenl the corn harvester is in use and it is desiredto discharge the corn into a wagon bed, the wagon is drawn along side the corn harvester.

yThe locking bolt 71 is withdrawn and the locking bar 68 raised, whereupon the tongue of the wagon is laid into the reoeivin membar 'formed by the bar 65 and t e upwardly extending members 66 and 67, as illustated, for instance, by dotted lines in The chain 73 is fastened to the tongue forwardly of the bar 20, while the chain 63 'is fastened to the tongue or to the wagon rearwardly of the bar 20.

The locking bar 68 is then lowered and the locking bolt 71 is permitted to enter the opening in the member 66,A whereby the tongue will be held against jumping out of i draft is fairly well distributed, and it is possible to readily hitch the wagon to they tractor in such a way as to permit the wagon to travel along side the corn harvester. This has, heretofore, been a rather diflicult thing to do, and the advantage of a suitable convenient, and comparatively inexpensive hitch by which said result can be accomplished is largely obvious.

Some changes may be made in the construction and arrangement of the parts of my combination hitch without departingl from the essential spirit and purpose of my invention, and it is m intention to cover by my claims any modi ed forms of structure or use of mechanicaly equivalents which may be reasonably included within their scope.
